Available Facilities
GMT offers a large panel of wind tunnels, for aerodynamic and acoustic test, covering very low Mach number to hypersonic Mach numbers.
Wind tunnels are located in 3 different areas in France: Modane-Avrieux, Le Fauga-Mauzac (near Toulouse) and Saclay (close to Paris).
- 5 continuous wind tunnel covering Low speed (few m/s) up to Mach 3.1,
- 3 blow-down wind tunnels covering Mach 0.1 up to Mach 21,
- 4 additional wind tunnels for specific applications.
